Definitions
SFP: the small form-factor pluggable (SFP) is a compact, hot-pluggable optical module transceiver used
for both telecommunication and data communications applications. It is a popular industry format jointly
developed and supported by many network component vendors. *
SFP+: the enhanced small form-factor pluggable (SFP+) is an enhanced version of the SFP that supports
data rates up to 10 Gbit/s. *
ATTENTION!
The MMU accepts SFP modules only because of the hardware limitation of the SFP slot.

6.8.1. SFP+ Interface for the Endpoints
The endpoint devices are built with 2x 10 GbE SFP+ ports to transmit the video streams between the receiver
and the transmitter.
The following methods can be applied to connect the endpoint devices to the network switch:
▪ 2x SFP+ transceiver modules up to 10Gbps bandwidth/modules. The modules can be singlemode
or multimode, built with LC duplex connectors or BiDi modules. The maximum allowed fiber optical
cable length depends on the installed SFP+ modules. Always check the specification of the module.
▪ 2x 10 GbE DAC cables

INFO: The maximum available bandwidth with the endpoint device is 20 Gbps which requires 2x 10 GbE
SFP+ module or DAC cable to install. If one 10 GbE SFP+ module or DAC cable is installed only but the
signal is 4K@60 Hz (which requires 14 Gbps to transmit), the signal transmission will be disabled.
INFO:
For more details of the installation steps of SFP+ modules see the
section.
6.8.2. SFP Interface for the MMU
The UBEX-MMU-X200 matrix management unit has one 1 GbE SFP module slot for the fiber optical connection
via the network switch.
The following methods can be applied to connect the MMU to the switch:
▪ 1x SFP transceiver module up to 1 Gbps bandwidth. The module can be singlemode or multimode,
built with LC duplex connectors or BiDi modules. The maximum allowed fiber optical cable length
depends on the installed SFP modules. Always check the specification of the module.
▪ 1x 1 GbE DAC cable

INFO: For more details of the installation steps of SFP modules see the
section.

SFP / SFP+ Slot Connection
The UBEX F-series and R-series endpoint models are built with two equivalent 10 GbE fiber optical channels
which are based on a redundant operating principle. It means both 10 GbE fiber optical connections are able
to take its place of the other one in case of a connection loss. For example if one of the two SFP+ modules
is pulled out during the operation, the AV transmission is going on.

ATTENTION! The optical connection redundancy is available only in case of one or two HDMI signals where
the sum of the required bandwidth is not greater than 10 Gb/s. Please check the
the Resolutions section for the details.

INFO: If two HDMI signals are transmitted where the sum of the bandwidth is greater than 10 Gb/s, there
are limitations in the signal transmission on transmitter and receiver sides. See more details about it in
the Bandwidth Limitation section.
The UBEX matrix cloning is a simple method to save the database of the matrix and the configuration
settings of the MMU to a backup file. This file can be saved to your computer and can be restored to the
MMU later. See more information about the content of the backup file in the
